3 Claims.

This invention relates to a carpenters combined tri-square and bevel-square, the primary object of the invention being to provide a tool of this character which may be adjusted for use in measuring and indicating the line on which a beam is to be cut, in the accurate formation of the side cut of hips, valleys and jacks of hip and valley roofs.

An important object of the invention is to provide a tool of this character having adjustable means, whereby the blade thereof may be moved to Various angular positions with respect to the body portion, thereby adapting the device for use either as a tri-square or bevelsquare, for making various types of cuts.

With the foregoing and other objects in view, which will appear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the inven- 1 tion.

Referring to the drawing:

Figure 1 is a side elevational view of a tool constructed in accordance with the invention, a portion of the tool being shown in section, illustrating the connection between the body portion o the tool and blade mount. Figure 2 is a plan View of the tool.

Referring to the drawing in detail the' tool comprises a body portion indicated by the reference character 5, which is rectangular in cross section, presenting flat side faces, to be positioned against the board or beam to be ruled and marked with the tool.

The body portion is formed with a bore extending throughout the length thereof and arranged centrally of the body portion, the bore being designed to accommodate the bolt 6, which is shown as extending therethrough, the lower threaded end of the bolt being supplied with a wing nut 1.

On the upper end of the body portion 5 is a plate 8 which is provided with graduations 9 that cooperate with the finger ID indicating various angles of cuts of hips, valleys and jacks of hip and valley roofs. The finger l0 forms a part of the plate II that issecured to the lower end of the post or base I2, by means of the screws I3. The plates 8 and II are formed with registering openings through which the bolt 6 extends, the head of the bolt engaging the plate I I,

as clearly shown by Figure 1 of the drawing. Thus it will be seen that by loosening the wing nut l, the post or base I2 is free to rotate on the upper end of the body portion 5. After the adjustment has been made, the wing nut 'I is operated to tighten the post or base I2 on the end of the body portion to hold it in its adjusted position.

The upper or free end of the base I2 is slotted, the slot extending inwardly towards the base 5, an appreciable distance. The slot provides a space for the right angled end I4 of the pivoted blade I5 which is shown as mounted in the slot.

Registering openings are formed through the post orV base I2, and accommodate the bolt I6 that extends through an opening in the right angled end I4 of the blade. A Wing nut Il is mounted on the threaded end of the bolt I6 and affords means whereby the blade I5 may be` securely clamped and held in its positions of adjustment.

In the use of the tool, the post or base I2 is rotated with respect to the body portion 5 until the blade I5 has been moved to the proper angular position for the cut to be ruled. The tool is now positioned against the board or beam to be cut, with the side'face'of the body portion resting against the side face of the board or beam. The blade I5 is now extending across the edge of the beam or board, and by moving a pencil along the lower edge of the blade, a mark may be made on which an accurate cutting of the beam or board may be made to insure a true and accurate formation of a joint, in the construction of hips, valleys and jacks forhip and valley roofs.

Having thus described the invention, what is claimed is:

1. A tool of the class described, comprising an elongated body portion, a bolt extending longitudinally through the body portion, a blade base mounted on one end of the body portion, a plate secured to the base and having an opening formed therein, the head of the bolt resting against the plate holding the base to the body portion, a nut on the threaded end of the bolt and adapted to draw the base into close engagement with the body portion, a blade pivotally mounted on the base and adapted to cooperate with one side of the body portion in making a measurement, and means for securing the blade in various positions of adjustment.

2. A tool of the class described, comprising an elongated body portion, a bolt extending longitudinally through the center of the body porand having a central longitudinal bore, a blade base member having an opening, a bolt positioned in the opening of the base member and extending through the bore, adjustably securing the base member to the body portion, a blade pivotally connected to the base member and adapted to move to various angular positions with respect to the body portion, and means for securing the blade and base member in their posi- 10 tions of adjustment.
